Three types of forecasts are available from the point-click Point
forecast pages. All of the forecasts are gridpoint based, and prepared
by National Weather Service forecasters. In most areas the grid resolution
is 5km; however in mountaineous areas a finer resolution is used, usually
2.5km. Below is a description of the forecasts available in the interactive
forecast pages, and how to use them.

1. 7-Day Text Forecasts

The 7-day text forecasts provide a text-based look at the forecast for
the next 7 days. Near the top of the page a quick-glimpse of the weather
is available, which provides a picture, a one or two word description
of the expected weather, and the forecast high or low temperature.

Below this, an actual worded forecast is displayed with more detail. In
addition, you will find any current watches, warnings, or advisories in
effect listed here, along with current weather conditions, and links to
more available weather information for the selected area.2. Meteorograms

A meteorogram is an element-time look at weather conditions for the next
48 hours. If this forecast type is selected the user can also select which
weather elements they would like to see the forecast for by selecting/de-selecting
the weather element check boxes.

The following weather elements are presented in a linear format, tracing
the changes on an hourly basis,

Special note concerning wind speed and direction
In addition to the linear trace of the magnitude of the wind, the wind
direction is also shown using what is called a "wind barb".
The wind barb is always point in the direction that the wind is coming
from. The magnitude of the wind on a wind barb is calculated using the
attached flags at the end of the wind barb. A long wind flag is 10 mph,
a short wind flag is 5 mph, and a triangle wind flag is 50 mph. So, if
you see a wind barb with two long flags and one short flag on it, the
forecast wind speed would be 25 mph.

The following weather elements are presented in bar graph format, giving
the chances for each type of weather event categorically.

3. Digital/Tabular

The digital/tabular forecast pages provide hourly forecast information
in tabular format for weather conditions in the next 120 hours. If this
forecast type is selected the user can also select which weather elements
they would like to see the forecast for by selecting/de-selecting the
weather element check boxes.
